Electronic based high-voltage measuring transformers

Slomovitz, Daniel

Resumen:

A new electronic system to assist high-voltage measuring transformers is proposed. This system compensates the voltage drops in the series impedances of the transformer, which are the main cause of errors at power frequency. The nonlinear behavior of the magnetizing branch has no influence on the results. The proposed compensator also reduces the influence of the burden impedance on the transformer errors. Any auxiliary winding or core is not necessary so that conventional units can be compensated.
